【摘要】 以废弃油茶籽粕作为碳源,将MoS₂负载于生物质碳上,再涂覆聚多巴胺盐酸盐构建复合型生物质碳/MoS₂电极材料。研究不同MoS₂含量复合电极材料的电化学储锂性能。SEM观察结果表明,该复合材料具有以MoS₂作为夹层的三维泡沫状结构。XRD和HRTEM测试结果表明MoS₂的层间距增大。XPS分析结果显示,活性材料中已形成Mo—N键。电化学性能测试结果表明,MoS₂含量为63%的活性材料在100m A/g电流密度下具有较高的初始比容量（1434m A·h/g）。在大电流、长循环条件下此电极材料呈良好的循环稳定性,其容量保持率接近100%,在电化学动力学过程中具有较好的锂离子脱嵌能力。更多还原

【Abstract】 Molybdenum disulfide（MoS₂） was loaded on biocarbon using waste camellia dregs（CDs） as the carbon source, which was further coated with dopamine hydrochloride to construct biocarbon/MoS₂ electrode composites. The electrochemical lithium storage performance of the composites with different MoS₂ contents was investigated. SEM results demonstrated that the composite had a three-dimensional foam-like structure with MoS₂ as the interlayer. XRD and HRTEM tests revealed that MoS₂ interlayer spacing in the composite was expanded. XPS analysis showed that new Mo—N bonds were formed in the active material. The electrochemical tests showed that the composite with a MoS₂ content of 63% had a high initial specific capacity of 1434 mA·h/g at a current density of 100 mA/g. After a long cycle at a high current, it also showed good cycling stability and the capacity retention was nearly 100%. In addition, it had good lithium ion deintercalation ability in the electrochemical kinetics test.更多还原
